Construction of the dam began in the Soviet era, in 1976, but was abandoned in 1993 after the collapse of the Soviet Union. Over three decades only preliminary construction has been carried out on the dam. Due to its controversial state, construction was suspended in August 2012 pending World Bank reports. The project was restarted by the Tajik government in 2016. The power plant's first unit was commissioned in November 2018 and second in September 2019, both on lower hydraulic head.
The dam has drawn complaints from neighboring Uzbekistan, which fears it will negatively impact its lucrative cotton crops. The dispute over the project has contributed significantly to bitter relations between the two former Soviet republics.
